Description

Technical Field

[0001] This invention relates to the field of mobile shelving shockproof technology, specifically to a shockproof mobile shelving unit. Background Technology

[0002] The shockproof mobile shelving unit of this invention is a protective device specifically designed for art collection. It can provide more professional protection and management, meeting the special needs of art collection. This shockproof mobile shelving unit can reduce the impact of earthquakes and vibrations on art, reduce the risk of damage and destruction, and effectively protect the integrity and value of art.

[0003] Compared to existing technologies that use specially designed vibration isolation brackets and additional damping materials to reduce the vibration transmission of mobile shelving, this method can effectively improve the shock resistance of mobile shelving, but it also has the following drawbacks: specially designed vibration isolation brackets and additional damping materials will increase the manufacturing and installation costs of the equipment, and the vibration isolation brackets and additional damping materials specially designed for different models of mobile shelving cannot be adapted to various main bodies. In addition, the additional installation of other devices requires regular maintenance and replacement, which increases the maintenance costs and workload of the equipment.

[0004] Furthermore, existing mobile shelving units typically employ adjustable shelves and partitions to accommodate items of different sizes and weights and ensure they are not damaged when placed on the shelves. However, when the main body of the mobile shelving unit is subjected to impact or external force, even if the shelves and partitions can protect the internal items from damage, the mobile shelving unit itself will be damaged, affecting the stability and structural integrity of the entire unit. When the mobile shelving unit itself is damaged and becomes unstable, it can also cause items to tilt, fall, or be damaged, posing potential risks to personal safety and the safety of the items.

[0005] Therefore, in view of this, the present invention proposes a vibration-resistant mobile shelving unit to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a vibration-resistant mobile shelving unit, thereby resolving the technical issues raised in the background section.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a vibration-resistant mobile shelving unit, comprising a mobile shelving unit body, a storage top installed on the upper surface of the mobile shelving unit body, a storage compartment formed by horizontal and vertical partitions inside the mobile shelving unit body, a cabinet vibration-resistant mechanism symmetrically arranged on the left and right sides of the mobile shelving unit body, and an inner protective mechanism arranged on the top of the mobile shelving unit body.

[0008] The cabinet vibration damping mechanism is used to reduce and change the direction of force when the main body of the mobile shelving unit is subjected to force.

[0009] The inner protective mechanism is used to automatically trigger protection when the internal force of the mobile shelving unit exceeds the limit.

[0010] Furthermore, the cabinet vibration damping mechanism includes inner partitions symmetrically fixedly connected to the left and right sides of the mobile shelving unit. The surfaces of the inner partitions are evenly provided with through slots. Each through slot has a load-bearing shaft fixedly connected to its inner wall. Each load-bearing shaft has a hinge frame symmetrically slidably connected to its outer wall. Each hinge frame has a return spring fixedly connected to its side closest to each other. The return spring is integrally sleeved on the outer wall of the load-bearing shaft. Each load-bearing shaft has an adjusting shaft symmetrically fixedly connected to its outer wall. The end of the adjusting shaft furthest from the load-bearing shaft is hinged to the hinge frame. Each inner partition has a sliding rod symmetrically slidably connected to its outer wall. Each sliding rod has a buffer spring sleeved on its outer wall. The end of the buffer spring furthest from the inner partition is fixedly connected to an outer contact plate.

[0011] Furthermore, the ends of the hinge frames away from the load-bearing shaft are fixedly connected to the outer contact plate, and the hinge frames are initially in a retracted state.

[0012] Furthermore, the adjusting shaft is a multi-section telescopic structure. The adjusting shaft initially remains in an extended state, and the adjusting shaft and the hinge frame always form a right-angled triangle.

[0013] Furthermore, polyurethane foam material is installed at the connection points between the inner partition and the slide rod, and the two ends of the buffer spring are fixedly connected to the inner partition and the outer contact plate, respectively.

[0014] Furthermore, the inner protective mechanism includes dual-axis motors symmetrically installed inside the silo top. Each output shaft of the dual-axis motor is connected to a drive belt. The end of each drive belt away from the dual-axis motor is connected to a partially threaded shaft. The partially threaded shaft is rotatably connected to a transverse partition inside the silo top. Positive magnetic chucks are uniformly installed on the outer wall of the partially threaded shaft. A limit frame is fixedly connected to the outer wall of the positive magnetic chuck. Negative magnetic chucks are fixedly connected to the upper surface of the limit frame. A movable main shaft is uniformly slidably connected inside the transverse partition in the silo top. A secondary support is uniformly hinged to the outer wall of the movable main shaft. A linkage gripper is uniformly hinged to the end of each secondary support away from the movable main shaft.

[0015] Furthermore, the dual-axis motor is specifically a dual-axis drive motor on the same side in the prior art. The outer wall of the partial threaded shaft is provided with threaded grooves at equal intervals. The positive magnetic chuck and the limiting frame are specifically sleeved at the position of the threaded groove on the outer wall of the partial threaded shaft. The partial threaded shaft, the positive magnetic chuck, and the limiting frame form a ball screw structure. The control switch of the dual-axis motor is located on the moving path of the slide rod.

[0016] Furthermore, the positive magnetic chuck is initially located directly above the moving main shaft, and the end of the moving main shaft near the positive magnetic chuck is made of positive magnet material. The linkage gripper is initially in an extended state, and the linkage gripper is initially attached to the lower surface of the internal transverse partition of the top of the compartment.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) Based on the analysis of the overall force probability and overall shape arrangement of the main body of the mobile shelving unit, this device symmetrically installs external contact plates on its left and right sides. Compared with the existing technology that uses specially designed vibration isolation brackets and reduces the vibration transmission of the equipment by adding damping materials, this device first uses horizontally installed buffer springs to slow down and buffer the external contact plates by their own elasticity. Then, it uses the hinge frame that expands after being subjected to force to transform the horizontal squeezing force on the left and right sides of the main body of the mobile shelving unit into vertical transmission. By changing the direction of the squeezing force, the squeezing force on the artwork inside the main body of the mobile shelving unit can be avoided, and the impact and damage risk caused by the shaking and vibration of the main body of the mobile shelving unit can be reduced. Compared with adopting a complex method to reduce the squeezing force, changing the direction of force is easier to achieve and maintain. It does not require additional devices or systems to reduce the squeezing force, but achieves the direction of force through reasonable structural design. Moreover, changing the direction of force in this device can make the main body of the mobile shelving unit better adapt to various accidental squeezing situations. No matter which area the pressure is applied to on the left and right ends, it can be guided to a safe position through the cooperation between the hinge frame and the slide bar to provide more comprehensive protection.

[0019] The device has symmetrically fixed adjustment shafts at the upper and lower ends of the load-bearing shaft. The adjustment shaft is a multi-section telescopic structure. Initially, it is in an extended state and always forms a right-angled triangle with the hinge frame. Firstly, the right-angled triangle structure has good mechanical stability, which can ensure that the hinge frame is not easily deformed when subjected to external forces, thus maintaining its own stability and reliability of movement. The multi-section telescopic structure design allows the adjustment shaft to extend and retract under different conditions to adapt to different stress conditions, increasing the stress adaptability and flexibility of the hinge frame.

[0020] Polyurethane foam material is installed at the connection points between the inner partition and the sliding rod in this device. Due to the high elasticity and excellent cushioning performance of polyurethane foam material, when the main body of the mobile shelving unit is hit by personnel, equipment or other objects, the polyurethane foam material can effectively absorb and disperse the impact force, thereby significantly reducing the force transmitted to other components and protecting the internal structure. Furthermore, based on the characteristic that the foam material automatically fills the gaps when under force and automatically returns to its original shape when it is not under force, this means that after being impacted, the material can quickly restore its original shape and performance, ensuring the long-term stability and reliability of the device.

[0021] (2) When the two sides of this device are subjected to impacts exceeding its own force range, the safety mechanism can be automatically triggered in time. The operation of the dual-axis motor drives the moving main shaft and the linkage gripper to move and change state. Finally, the linkage gripper changes from the extended state to the retracted state that moves towards the surroundings, closely surrounding the outer perimeter of the items placed inside to provide a limiting protection effect, preventing items from being damaged or falling due to impact, thus improving the safety performance of the mobile shelving unit. Moreover, the entire safety mechanism is automatically triggered when subjected to force without human intervention. When the mobile shelving unit is subjected to abnormal impact, it can respond quickly and activate protective measures, reducing the risk caused by untimely human operation. At the same time, this device can take protective measures for all items almost simultaneously, which greatly improves the efficiency and response speed of protection. In the event of an accident or impact, there is no need to trigger individual protective mechanisms one by one, allowing the entire device to quickly enter the working state to protect all items.

[0022] Furthermore, since the linkage grippers do not protrude from the structural surface in their initial state, they do not affect the overall aesthetics. This is especially important for scenarios that require a clean appearance or to meet specific design requirements. Additionally, the linkage grippers are initially attached to the surface of the warehouse top and do not occupy additional space. This is particularly important for mobile shelving units with limited space, allowing the device to minimize space occupation and maximize space utilization without sacrificing protective effects.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Embodiments of the present invention

[0037] Please refer to Figure 1 - Figure 2 As shown, a vibration-resistant mobile shelving unit includes a mobile shelving body 1, a storage top 11 installed on the upper surface of the mobile shelving body 1, a storage compartment formed by horizontal and vertical partitions inside the mobile shelving body 1, a cabinet vibration-resistant mechanism 2 symmetrically arranged on the left and right sides of the mobile shelving body 1, and an inner protective mechanism 3 arranged on the top of the mobile shelving body 1.

[0038] Please refer to Figure 3 - Figure 5As shown, the cabinet anti-vibration mechanism 2 includes inner partitions 21 symmetrically fixedly connected to the left and right sides of the mobile shelving body 1. The surface of the inner partitions 21 is evenly provided with through grooves 22. Each through groove 22 has a load-bearing shaft 23 fixedly connected to its inner wall. Each load-bearing shaft 23 has a hinge frame 24 symmetrically slidably connected to its outer wall. Each hinge frame 24 has a return spring 25 fixedly connected to one side of each other. The return spring 25 is entirely sleeved on the outer wall of the load-bearing shaft 23. Each load-bearing shaft 23 has an adjusting shaft 26 symmetrically fixedly connected to its outer wall. The end of the adjusting shaft 26 furthest from the load-bearing shaft 23 is hinged to the hinge frame 24. The outer walls of the inner partitions 21 are symmetrically slidably connected to the hinge frame 24. The outer walls of rod 27 and slide rod 27 are fitted with buffer springs 28. The end of buffer spring 28 away from inner partition 21 is fixedly connected to outer contact plate 29. The end of hinge frame 24 away from load-bearing shaft 23 is fixedly connected to outer contact plate 29. The hinge frame 24 is initially in a retracted state. The adjusting shaft 26 is a multi-section telescopic structure. The adjusting shaft 26 is initially in an extended state. The adjusting shaft 26 and hinge frame 24 are always in a right-angled triangle state. Polyurethane foam material is installed at the connection position between inner partition 21 and slide rod 27. The two ends of buffer spring 28 are fixedly connected to inner partition 21 and outer contact plate 29 respectively.

[0039] Specifically, this device first uses the horizontally installed buffer spring 28 to slow down and buffer the external contact plate 29 by its own elasticity. Then, it uses the hinge frame 24, which expands after being subjected to force, to convert the horizontal squeezing force on the left and right sides of the mobile shelving body 1 into vertical transmission. By changing the direction of the squeezing force, the squeezing force on the artwork inside the mobile shelving body 1 can be avoided, and the risk of impact and damage caused by the shaking and vibration of the mobile shelving body 1 can be reduced.

[0040] Please refer to Figure 6 - Figure 11As shown, the inner protective mechanism 3 includes dual-axis motors 31 symmetrically installed inside the silo top 11. Each output shaft of the dual-axis motor 31 is connected to a drive belt 32. The end of each drive belt 32 away from the dual-axis motor 31 is connected to a partially threaded shaft 33. The partially threaded shaft 33 is rotatably connected to the internal transverse partition of the silo top 11. Positive magnetic chucks 34 are evenly installed on the outer wall of the partially threaded shaft 33. A limit frame 35 is fixedly connected to the outer wall of the positive magnetic chuck 34. Negative magnetic chucks 36 are fixedly connected to the upper surface of the limit frame 35. A movable main shaft 37 is evenly slidably connected inside the transverse partition of the silo top 11. A bracket 38 is evenly hinged to the outer wall of the movable main shaft 37. The end of the bracket 38 away from the movable main shaft 37... The linkage gripper 39 is evenly hinged. The dual-axis motor 31 is specifically a dual-axis drive motor on the same side in the prior art. The outer wall of the partial threaded shaft 33 is provided with threaded grooves at equal intervals. The positive magnetic chuck 34 and the limiting frame 35 are specifically sleeved at the position of the threaded groove on the outer wall of the partial threaded shaft 33. The partial threaded shaft 33, the positive magnetic chuck 34, and the limiting frame 35 form a ball screw structure. The control switch of the dual-axis motor 31 is located on the moving path of the slide bar 27. The positive magnetic chuck 34 is initially located directly above the moving main shaft 37. The end of the moving main shaft 37 near the positive magnetic chuck 34 is made of positive magnet material. The linkage gripper 39 is initially in an extended state. The linkage gripper 39 is initially attached to the lower surface of the internal transverse partition of the top of the bin 11.

[0041] Specifically, when the two sides of this device are subjected to impacts exceeding their own force range, the safety mechanism can be automatically triggered in time. The operation of the dual-axis motor 31 drives the moving main shaft 37 and the linkage gripper 39 to move and change state, ultimately causing the linkage gripper 39 to change from an extended state to a retracted state that closely surrounds the outer perimeter of the internally placed items to provide a limiting protection function.

[0042] The following are the complete usage steps and working principle of the above embodiments:

[0043] like Figure 1 and Figure 2 As shown, since the main body 1 of this device and the existing mobile shelving is mostly designed as a rectangle and is placed in a concentrated manner, when the device is placed in a concentrated manner, there will be a certain gap between each column for personnel and equipment to move. This layout makes the two sides of the device, namely the ends and side panels, more exposed than other parts of the device, and therefore more susceptible to impacts from personnel, equipment or other objects. In addition, since the front and rear sides of the device have a large area, the force per unit area will be relatively small, thereby enhancing its pressure resistance or impact resistance to a certain extent. To solve the defects of the above-mentioned device, the cabinet anti-vibration mechanism 2 is now symmetrically arranged on the left and right sides of the main body 1 of the mobile shelving.

[0044] The cabinet anti-vibration mechanism 2, used to reduce and change the overall force direction of the mobile shelving unit 1, is specifically used as follows:

[0045] like Figure 2 , Figure 3 as well as Figure 5 As shown, since the outer contact plates 29 are symmetrically slidably connected to the left and right sides of the mobile shelving unit 1 via the slide rods 27, when the sides of the mobile shelving unit 1 are impacted by personnel, equipment, or other objects, the outer contact plates 29 will first reduce the horizontal transmission of the compressive force by relying on the buffering force of the buffer springs 28 sleeved on the outer wall of the slide rods 27, and then... Figure 3 and Figure 4 As shown, since the inner partition 21 is symmetrically and fixedly connected to the load-bearing shaft 23, and the outer wall of the load-bearing shaft 23 is symmetrically and slidably connected to the hinge frame 24, and the end of the hinge frame 24 away from the load-bearing shaft 23 is fixedly connected to the outer contact plate 29, when the outer contact plate 29 relies on the buffer force of the buffer spring 28 to reduce its own pressure horizontally, the pressure on the outer contact plate 29 will simultaneously act on the surface of the hinge frame 24, thereby causing the hinge frame 24, which was initially in a state of mutual contraction, to change to a state of expansion to the upper and lower sides. Since the outer wall of the load-bearing shaft 23 is sleeved with a return spring 25, and the upper and lower ends of the return spring 25 are fixedly connected to the hinge frame 24, when the hinge frame 24 moves and expands in opposite directions at the same time, it will continuously stretch the return spring 25 to reduce the pressure it receives, and through the expansion direction of the return spring 25, it will convert and transmit the horizontal pressure it receives to the vertical direction.

[0046] The inner protective mechanism 3, which automatically triggers protection when the internal force on the main body 1 of the mobile shelving unit exceeds the limit, is used in the following way:

[0047] like Figure 6 and Figure 7 As shown, the control switch of the dual-axis motor 31 located inside the warehouse top 11 is located on the moving path of the slide bar 27. Therefore, when the outer contact plates 29 on both sides of the mobile shelving unit 1 exceed their own force range, causing the slide bar 27 to over-displace, the slide bar 27 will then contact the control switch of the dual-axis motor 31, thereby triggering its operation. Figure 8 and Figure 9As shown, both output shafts of the dual-axis motor 31 are connected to the local threaded shaft 33 via a transmission belt 32. Therefore, when the dual-axis motor 31 is triggered to run, the local threaded shaft 33 will rotate synchronously with it through the drive of the transmission belt 32. Since the outer wall of the local threaded shaft 33 is provided with threaded grooves at equal intervals, and the positive magnetic chuck 34 and the limiting frame 35 are specifically sleeved at the position of the threaded groove on the outer wall of the local threaded shaft 33, and the local threaded shaft 33, the positive magnetic chuck 34, and the limiting frame 35 form a ball screw structure, when the local threaded shaft 33 rotates, it will drive the positive magnetic chuck 34 and the limiting frame 35 at its threaded part, so that the two move linearly along the outer wall of the local threaded shaft 33 at the same time.

[0048] like Figure 10 As shown, since the positive magnetic chucks 34 are initially located directly above the moving main shaft 37, when the positive magnetic chucks 34 move and are offset from the moving main shaft 37, the negative magnetic chuck 36 moves with the limiting frame 35 to directly above the moving main shaft 37. Because the end of the moving main shaft 37 closest to the positive magnetic chucks 34 is made of a positive magnet, when the negative magnetic chuck 36 aligns with it, the free electrons inside the end of the moving main shaft 37 are affected by the magnetic field generated by the negative magnetic chuck 36. This causes the moving main shaft 37 to be attracted by the magnetic field of the negative magnetic chuck 36, thus causing the moving main shaft 37 to move along the inner wall of the limiting frame 35 towards the negative magnetic chuck 36. Figure 11 As shown, since the linkage grippers 39 are all hinged to the moving main shaft 37 through the sub-brackets 38, and the linkage grippers 39 are initially in an extended state and are attached to the lower surface of the internal transverse partition of the top of the warehouse 11, when the moving main shaft 37 moves upward, it will drive the linkage grippers 39 through the sub-brackets 38, causing them to change from the initial extended state to a retracted state that moves towards the surroundings. At this time, the retracted linkage grippers 39 can be located on the periphery of the items placed inside the main body of the mobile shelving unit 1, thereby achieving a limiting and protective function.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
